The objective of this award is to provide partial travel support for researchers from the United States working in the area of tribology to attend and give invited presentations at the Fifth Conference on Multiscale Materials Modeling Conference 2010, which will be held in Freiburg im Breisgau, Germany, October 4-8, 2010. The title of the symposium in which they will present their work is "Tribology: Understanding Friction, Lubrication and Wear across the Scales." Deliverables include planned conference proceedings from the symposium that will be published in the European Physical Journal.
This symposium will form a unique platform that unites modelers and experimentalists to discuss the opportunities and challenges multiscale modeling offers for all kind of tribological issues. This will benefit the field because the performance of macroscale machines is governed by a variety of nanoscale mechanical and chemical processes at moving interfaces. This makes tribology - the science of interacting surfaces in relative motion - inherently multiscale. Consequently, modeling utilizes the complete MMM toolbox including electronic structure calculations, molecular dynamics, mesoparticle methods and continuum mechanics in order to study the underlying chemical, mechanical and fluidic processes on all length scales. It is anticipated that the unique focus of the symposium on the multiscale aspects of tribology will enhance scientific understanding of the field.
A symposium titled "Tribology: Understanding Friction, Lubrication and Wear across the Scales" was held at the Mutliscale Materials Modeling Conference 2010 (MMM2010) in Freiburg im Breisgau, Germany, October 4-8, 2010. The symposium co-organizers were Susan Sinnott (University of Florida), Michael Moseler (University of Freiburg), and Momoji Kubo (Tohoku University). The plenary talk for the symposium was given by Uzi Landman and was titled "Molecular organization, dynamics and dissipation in nanojunctions, nanofluids and membranes". This presentation was attended by all of the attendees of the MMM2010 conference (about 500 people). In addition, 31 oral (invited and contributed) presentations and 12 poster presentations were given by researchers from around the world at the symposium. The funds for this project were used to support the travel of Uzi Landman, in addition to Mark Robbins, Susan Sinnott, William Curtin, Greg Sawyer, Rob Carpick, and Izabela Szlufarska, all from the United States. Their presentation times over the course of the symposium and their presentation titles are as follows: Invited 10/4/2010, 11:00 AM Mark Robbins, "Connecting atomistic and continuum models of contact area, stiffness, and friction in single and multi-asperity contacts" Contributed 10/5/2010, 2:40 PM Susan Sinnott, "Tribology at the nanoscale: Insights from atomistic simulations" Invited 10/6/2010, 12:00 PM William Curtin, "Interface friction in carbon-nanotube/diamond nanocomposites" Invited 10/7/2010, 2:00 PM Greg Sawyer, "Nanoscale wear in materials tribology" Invited 10/7/2010, 4:20 PM Rob Carpick, "From atomic membranes to molecular adsorbates: How interfacial atomic structure influences nanotribology in carbon-based systems" Invited 10/7/2010, 5:00 PM Izabela Szlufarska, "Wear of nanocrystalline ceramics by atomistic simulations" Poster, 10/5-10/6/2010 Susan Sinnott, "Atomistic simulations of tribology at sliding MoS2 surfaces" Information about the symposium was disseminated through email announcements and through the symposium website: www.mmm2010.de/program/symposia/tribology/ .
